ABIO10 PGTW 0805002. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED
NEAR 15.3S 35.6E, IS NOW LOCATED NEAR 15.4S 34.8E, APPROXIMATELY 436
NM NORTHWEST OF EUROPA ISLAND. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS AN OBSCURED LOW LEVEL CIRCULATION (LLC) WITH A BROAD
AREA OF DEEP CONVECTION TO THE EAST. A 080336Z SSMIS F-17 91GHZ
MICROWAVE IMAGE SHOWS MID-LEVEL CONVECTION OVER THE LLC WITH DEEPER
CONVECTION TO THE SOUTHEAST ASSOCIATED WITH A SOUTHERNLY INFLOW
CHANNEL. 98S IS CURRENTLY EXPERIENCING EXCELLENET WESTWARD OUTFLOW
AND VERY LOW (5 TO 10 KNOTS) VERTICAL WIND SHEAR (VWS). SEA SURFACE
TEMPERATURES ARE WARM (28 TO 29 CELSIUS) IN THE MOZAMBIQUE CHANNEL.
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 98S WILL TRACK OVERWATER
AND RAPIDLY INTENSIFY WHILE SHARPLY TURNING SOUTH. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS MEDIUM.
      (2) AN AREA OF CONVECTION (INVEST 99S) HAS PERSISTED NEAR
10.7S 114.5E, APPROXIMATELY 560 NM EAST-SOUTHEAST OF JAKARTA.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 080106Z GMI 89GHZ
MICROWAVE IMAGE SHOW A PERSISTENT BALL OF DEEP CONVECTION OVER AND
OBSCURING THE LLC. 99S IS CURRENTLY IN A VERY FAVORABLE ENVIRONMENT
WITH EXCELLENT POLEWARD OUTFLOW, VERY LOW (5 TO 10 KNOTS) VWS, AND
VERY WARM (29 TO 30 CELSIUS) SST. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT 99S WILL CONTINUE TO TRACK WESTWARD BEFORE BEGINNING
TO RECURVE SOUTHWEST, ALL THE WHILE INTENSIFYING.  MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
      (3) NO OTHER SUSPECT AREAS.
